Access Denied

Win XP Pro with SP 1. All of my folders and files have only the following
attributes. Read-only (which is checked but greyed out on many of them),
and Hidden. I have no archive attribute. When I go to copy or move any
folder or file with the greyed out Read-only checked) I get this message:
Cannot copy DI_041305: Access is denied. Make sure the disk is not full or
write protected and that the file is not currently in use. Than I try to
uncheck the grey out Read-only attribute it asks me if I want to apply
this change to only that folder or to that folder and all of its
subfolders and files and if I check either option it say an error occurred
applying the attributes to the file: Access is denied and it gives the
following choice: Ignore, Ignore All, Retry and cancel. No matter what I
choice here it won't change the attribute or allow me to move the folder
or file.
How can I fix this so that I can move a folder or file to another
partition? It will allow me to delete the file or folder but that is it.
